<h3>Answer:</h3>
Density = 1.22 g.mL⁻¹
<h3>Solution:</h3>
Data Given:
Mass = 22.4 g
Volume = 18.3 mL
Density = ??
Formula used;
Density = Mass ÷ Volume
Putting values,
Density = 22.4 g ÷ 18.3 mL
Density = 1.22 g.mL⁻¹
I believe the answer is this (sorry if it’s a bit dark
Explanation:
Number of Cm neutrons = 242 - 96 = 146
The molarity of the solution made by dissolving 0.05 mole of HCl in 2 L of H₂O is 0.025 M
<h3>What is molarity? </h3>
Molarity is defined as the mole of solute per unit litre of solution. Mathematically, it can be expressed as:
Molarity = mole / Volume
<h3>How to determine the molarity </h3>
- Mole of HCl = 0.05 mole
- Volume = 2 L
- Molarity =?
Molarity = mole / Volume
Molarity = 0.05 / 2
Molarity = 0.025 M
Thus, the molarity of the solution is 0.025 M
